The Right Equipment for Every Job
Cousins Lawn Maintenance operates a full fleet of excavation equipment, allowing us to take on projects ranging from tight residential spaces to large-scale commercial sites. We understand that excavation is typically the first step in a larger project — we work efficiently and coordinate closely with plumbers, builders, and contractors so the next phase can proceed on schedule.
Yard Grading & Sloping
If you're like most New Jersey homeowners, your property sits on a slope — and every significant rain event tests whether that slope moves water away from your foundation or toward it. Poor grading is the leading cause of wet basements, eroded lawns, and foundation damage. Cousins Lawn evaluates your grade and reslopes where needed, correcting drainage paths before they create expensive structural problems.
Yard Leveling
Installing a pool, deck, patio, or shed requires a level, properly prepared surface. We handle site preparation for outdoor additions of any scale — clearing, grading, compacting, and finishing to your project's specifications. Surrounding landscape areas are restored and re-graded after installation.
Well Pipe Digging & Trenching
Installing, replacing, or repairing water supply lines and underground utilities requires precise, controlled excavation. We provide trenching and pipe support using mini-excavators, Bobcat equipment, and manual tools for areas where heavy equipment cannot reach.
Sewer Excavation
We work alongside homeowners and licensed plumbers to provide the excavation required for sewer line repair, replacement, and installation. We have the right equipment for the job, manage the dig with precision, and backfill and re-grade the area after the plumbing work is complete.
